We have given this set of our 4 1/2-year daughter on Christmas. Our daughter is thrilled. The bar for the Mirkophon keeps very bad if you want to adjust it in height. Has not got a screw so you can adjust it to the appropriate height, rod then drops down easily. I would be upset it, my daughter, she is not thrilled and that's the most important. However, it has only 2 melodies and rhythms to different. Through the microphone but I think it will certainly interressant. When you hold the expectancy adult low, it is a beautiful gift, children certainly have their fun factor.
